I work at a software provider. It's a young startup and it's my first job out of academia (I was a researcher before).
This being my first job at a company, needless to say, I was little knowledgeable at the technical stack and actual deployment nitty gritty, but I've developed them enough to be productive at my job (I'm a data scientist) and was recently promoted to a higher position where I lead a team of people.
I have had the feeling I face a lot of difficulty in getting ideas green-lit and having a group of people work on implementing them. It could be to do with my way of speaking, which can come off as lacking confidence, as I have a tendency to speak really low.
I've gotten feedback I lack the right "posture". I really want to improve in this regard and look more confident about my ideas so that I can see them implemented and have people get behind them, short of doing it all myself.
Could you give me some tips on how to appear more confident, and present better my ideas so that I can convince people they are worth doing?
